After installing openstack on CentOS with RDO package (installation I recommand as it is really easy) I had some issue with network : the bridges were not connected to the physical network and well configured so I was not able to communicate with any VM created.
Here is how I solved this issue …
A lot of you are coming to my blog for RF433 with Raspberry PI content (here). This article is a small part of a larger project I have. As part of this project I built a Raspberry Pi shield including an RF433 emitter and receiver. I could sell this shield to some of view if it make interest to you. To make it I selected emitters and receivers to get the best quality / price compromise. (read my other articles on this topic) I could sell it around 60€ + port.
Update : chek this article for all informations on the shield and buy it !
RF433 shield for Raspberry PI v0.1
My question to you is : would you be interested in a such thing ?
If yes : leave me a comment with your email address ( I’ll will remove this address before validating it )
RF433 Raspberry PI shield v1.0
Here is the Version 1.0 with antenna connector integrated to PCB.
Following the excellent OpenStack tutorial for OpenSuse you can find here I made some modification to make it works …
It’s not the first time I have some trouble to setup grub2 correctly with my nvidia raid system (also called fake-raid) … I did not find exactly why, but for sure i never try to install grub2 correctly from yast or in manual mode.
The first solution to find was : how to boot a fresh installed system when the bootloader has not been configured. The solution is here : http://www.supergrubdisk.org. This tool is really simple and so efficient to boot ! I recommend to have this in your linux emergency kit !
The second solution, once the system has start is to reinstall a bootloader. Here, in fact the solution is easy : destroy this f**** grub2 and replace it by the legacy really good grub ! lol
Then it works … last step to me: understand why gnome is taking so long to start ?!? or the answer is in the question …
I love Linux !

Many years ago, I was considering myself as a specialist of Makefiles … But now, I know that Makefile science is not like bicycle and you may loose all this knowledge as soon as you start to java Code …
So I’ve to go back to Makefile school again and here are some of my googling notes on this topic for my own remembers and why not yours !
The last step to use a ATMega328P / Yabbas from the Arduino IDE is to plug it with a FTDI cable (TTL RS232 over USB). Personnally, I’m using the TTL-232R-3V3 to do it. The first step was to create an adaptor to transform this cable output to the YABBAS pinout.
